Choose TNW Co., Ltd — Your Trusted Quality Supplier for Dissolved Air Flotation (DAF) Units
DAF systems act as core pretreatment equipment for oil removal and suspended solid separation, with surging market demand. However, the market is flooded with unreliable vendors, including OEM resellers without in-house production. Many buyers suffer from poor air dissolution efficiency, easily clogged releasers, thin rust-prone tank bodies and absent after-sales service, resulting in costly rework and unqualified discharge.
As a professional self-manufactured DAF producer, TNW Co., Ltd delivers stable, genuine DAF equipment without OEM or subcontracting. We have secured long-term cooperation with thousands of industrial and municipal projects nationwide through superior build quality.
1. In-House Full Production Ensures Reliable Build Quality
Unlike resellers that merely assemble outsourced parts, TNW runs complete production lines covering sheet metal processing, welding, assembly and commissioning. Every DAF unit passes three strict pre-delivery tests: water pressure test, air dissolution efficiency inspection and full machine trial run. No unqualified products are shipped out.
We never cut corners on raw materials: thick PP or standard 304 stainless steel for food and domestic wastewater; upgraded 316L stainless steel with passivation anti-corrosion treatment for corrosive chemical and electroplating wastewater. Modified filler inside air dissolving tanks lifts air solubility above 85%, forming fine uniform microbubbles for efficient pollutant adsorption. Wear-resistant, anti-corrosion chains and bearings for scum skimmers guarantee long underwater operation.
2. Customized Design for Diverse Wastewater Conditions
One-size-fits-all standard models fail to cope with varying oil content, pH values and suspended solids across industries. TNW’s technical team provides free site surveys and wastewater sample testing to tailor exclusive solutions:
Three mainstream types available: horizontal flow, shallow tank and partial recirculation; compact customized sizes fit limited space for plant renovation without large civil works.
Optional automation tiers: basic manual control for small workshops; premium PLC-linked models that coordinate with PAM dosing systems and screw presses for 24-hour low-labor operation.
Reinforced upgrades for harsh conditions: anti-clog releasers for high-oil printing wastewater, thick anti-corrosion layers for saline coastal water, heat tracing insulation for cold northern areas.
Long-term printing and food industry clients report stable 95% oil removal rates after switching to TNW customized DAF units, effectively lowering the load on subsequent biochemical systems.
3. Low Failure Rate Cuts Long-Term Operation Costs
Low upfront prices of generic DAFs lead to high hidden costs from frequent maintenance, chemical waste and production shutdowns. TNW’s optimized anti-clog releasers minimize disassembly and flushing frequency. Fully sealed tanks prevent odor leakage. High air solubility reduces PAM consumption by roughly 20%. With few wearing parts, properly operated TNW DAFs run 5–8 years without major overhauls, far outperforming generic units that leak or break down within 2–3 years.
Complete supporting packages combining TNW DAF, screw press and automatic dosing devices come pre-calibrated for seamless coordinated operation, eliminating coordination conflicts between separate suppliers.
4. Comprehensive After-Sales Support for Full Lifecycle
Many resellers disappear after sales, charging exorbitant fees for spare parts and repairs. TNW provides standardized full-cycle service:
Free pre-sales support: water testing, site surveys, solution design and case references.
Nationwide on-site installation, commissioning and operator training by professional technicians.
12-month warranty for core components (air dissolving pumps, skimmer drives, electric controls); genuine spare parts supplied at factory cost permanently.
Rapid fault response: remote troubleshooting for most minor issues, on-site rush repairs for critical breakdowns to limit downtime.
5. Proven Track Record with Massive Practical Project Cases
Real operating projects are the best proof of supplier credibility. TNW DAFs serve a wide range of sectors: municipal river purification, food slaughter, papermaking & printing, oily chemical machining, centralized catering wastewater and sand washing pretreatment. Running sites across all provinces are available for on-site inspection.
Numerous engineering contractors and wastewater operators place bulk repeat orders, driven by consistent treatment performance and dependable service, rather than cheap price competition.
Conclusion
DAF quality directly determines stable compliance of the whole wastewater treatment process. Picking cheap OEM vendors often brings expensive rectification, maintenance and shutdown losses. For durable, cost-balanced DAF equipment, TNW Co., Ltd stands out as a trusted self-production quality supplier.
